Officials of the Humane Society of Utah were pleased to learn this week that Ranger, the small dog violently kicked or thrown against a wall when burglars broke into his Riverton home while his owners were absent, has been released from the veterinary hospital, where his life hung in the balance for days, and is now back with his family. He is showing steady improvement, in spite of having suffered massive blunt trauma to his head, says owner Vicky Kunz.
